E.g. I convert umlauts to html entities or change symbols to ascii 
strings for file names. Instead of using the x-notation I typed the 
character itself. In the case of my script no character is over chr
(255). An example:
def foo (name):
   name = re.sub(r'®','_registered_',name)
   ... and many more substitutions

I think instead of r'' I should use u''?

It is possible to compile a RE object with the U flag:
matchreg = re.compile(u'®', re.U)
name = matchreg.sub('_registered_',name)

But maybe not neccessary. In my tests using any u-switches and u-
flags makes no difference. The only crucial things were 
1. using unicode().
2. using a coding flag as described in [1]
3. storing the python script as utf-8

For me using unicode() is ok.
